Tesla powerpacks power an island

Following on the renewables topic, here is an example of solar generation plus batteries. This one is deployed on the Hawaiian island of Kauai.

Tesla now offers a scaled down version of this for households, combining electricity-generating roof tiles and their powerwall home battery.

In theory, energy generation will move to very many points of local power generation vs the historical few, monolithic, power stations. Presumably the fundamental economics of energy generation & consumption will also dramatically change over the next couple of decades.
